It’s common to have uncertainty and worry in life. But sometimes, being scared to commit to ideas can cause them to fade out, losing benefits that were waiting on the other side.
If you have a goal, and a plan to get there, then have some faith in it. The best case is that it works. The worst case is that it fails, and you learn from the mistakes, improving your knowledge. Active is better than idle.
This obviously can’t apply to everything, as some processes can be life-threatening or malicious. But in general, it’s better to stick with an idea and get to a conclusion than to half-commit to it and end up forgetting.
